In optics, the relationship between image distance and object distance is described by the lens equation: 1/f 1/di 1/do, where f is the focal length of the lens, di is the image distance, and do is the object distance. This equation shows that as the object distance changes, the image distance also changes in a reciprocal manner.
The focal distance formula in optics is 1/f 1/do 1/di, where f is the focal length, do is the object distance, and di is the image distance. This formula is used to calculate the distance between the focal point and the lens or mirror.
To obtain this type of numerical information, it is necessary to use the Mirror Equation . The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows:1/f =1/d0 + 1/d1.
The degree of refraction is directly proportional to the frequency of the wave. This means that as the frequency of the wave increases, the degree of refraction also increases. This relationship is described by Snell's Law in optics.
The Rayleigh distance is the distance from a point source at which the light waves start to spread out and form a diffraction pattern. It is significant in wave optics because it helps determine the resolution and focus of optical systems, such as microscopes and telescopes.
The ratio of the height of an object to the height of its image is equal to the ratio of their distances from the lens or mirror. This relationship is defined by the magnification formula in optics, where M = -di/do (negative sign indicates inverted image). The ratio is dependent on the type of lens or mirror used and the placement of the object relative to the focal point.

Fiber optics is used for long distance communication due to its various advantages..
An aperature OS size a illluminated by a parallel beam sends diffracted light into a angle of approximately ~y/a. This is the angular size of the bright central maximum. In trevelling a distance z, the diffracted beam therefore acquires a width zy/a due to diffraction. this gives distance beyond which divergence of the beam of width a becomes significant. Therefore, z ~ a2/y we define a quantity ZF called the Fresenls distance by the following equation ZF= a2/yFor distance greater than ZF the spreading due to diffraction over that due to ray optics. The above equation shows that ray optics is valid in the limit of wavelength tending to zero.

There is really nothing infinite in real life. But there are several cases where for practical purposes, "infinity" is almost the same as "very large". One example is in optics, where it is not so much the distance from the lens to the object that matters, but the RECIPROCAL of the distance. In this distance, since the reciprocal of a very large number is close to zero, a far-away object (e.g., the Sun) can be approximated as "infinitely far away".
The ratio of the height of an object to the height of its image is equal to the ratio of their distances from the lens or mirror. This relationship is defined by the magnification formula in optics, where M = -di/do (negative sign indicates inverted image). The ratio is dependent on the type of lens or mirror used and the placement of the object relative to the focal point.
The relationship between refractive index and wavelength in optics is described by the phenomenon of dispersion. Refractive index is a measure of how much light is bent or slowed down when passing through a material. Different wavelengths of light are bent by different amounts, causing them to travel at different speeds and refract at different angles. This results in the separation of colors in a prism, as each color has a different wavelength and is bent by a different amount.
The Canon EF 70 300mm lens has an image stabilizer, diffractive optics, and a 58 mm filter diameter. It has a minimum focusing distance of 1.5m with an object magnification of 1:4.
